────────────────────────────────────────────────────────────────────────────
 
     TABLESEGCROSS must be specified in a program that defines a table as
     being smaller than 64K, but references beyond the end of the table,
     across a 64K segment boundary. This technique is commonly used in
     OSVS COBOL programs where the maximum size of a 01-level item is 32K.
 
     TABLESEGCROSS is ignored if you have enabled bound-checking, by
     specifying either BOUND or CHECK.
 
     Specifying TABLESEGCROSS makes the code produced for your program
     much less efficient. For smaller and faster code you should not
     specify TABLESEGCROSS.
